Implement inline expansion of the intrinsic elemental subroutine MVBITS with optional runtime checks for valid argument range. gcc/fortran/ChangeLog: * iresolve.c (gfc_resolve_mvbits): Remove unneeded conversion of FROMPOS, LEN and TOPOS arguments to fit a C int. * trans-intrinsic.c (gfc_conv_intrinsic_mvbits): Add inline expansion of MVBITS intrinsic elemental subroutine and add code for runtime argument checking. (gfc_conv_intrinsic_subroutine): Recognise MVBITS intrinsic, but defer handling to gfc_trans_call. * trans-stmt.c (replace_ss): (gfc_trans_call): Adjust to handle inline expansion, scalarization of intrinsic subroutine MVBITS in gfc_conv_intrinsic_mvbits. * trans.h (gfc_conv_intrinsic_mvbits): Add prototype for gfc_conv_intrinsic_mvbits. gcc/testsuite/ChangeLog: * gfortran.dg/check_bits_2.f90: New test.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
